Directions:

1. Create a login demo video or screenshots and login code.
2. Create a connection demo video or screenshots and connection code.

 NOTE: You should have your detailed design and a development schedule.  One of the first things that you should do is to verify connections.  If you have a database, a simple login page is good to verify that your software can connect and read from the database.  If you are using two or more components, it’s good to verify that you can get them to interact.  Component integration frequently takes more time than anticipated, and it’s a good idea to work that out early rather than leaving it for later.  If you are using any environments or components for the first time, it’s good to verify that you all your pieces working at a basic level before doing detailed work.  In any case, this is the week to start your development in earnest!

 In this exercise, you create a program for the sales manager at Computer Haven, a small business that offers motivational seminars to local companies. Figure 7-53 (SEE ATTACHED BELOW) shows the charge for attending a seminar. Notice that the charge per person depends on the number of people the company registers. For example, the cost for four registrants is $400; the cost for two registrants is $300. The program should allow the sales manager to enter the number of registrants for as many companies as needed. When the sales manager has finished entering the data, the program should calculate and display the total number of people registered, the total charge for those registrants, and the average charge per registrant. For example, if one company registers four people and another company registers two people, the total number of people registered is six, the total charge is $700, and the average charge per registrant is $116.67. 

 a.  Create an IPO chart for the problem and then desk-check the algorithm appropriately.

b.  List the input, processing, and output items, as well as the algorithm, in a chart similar to the one shown earlier in Figure 7-42. Then code the algorithm into a program.

c.  Desk-check the program using the same data used to desk-check the algorithm.

d.  If necessary, create a new project named Advanced25 Project, and save it in the Cpp8Chap07 folder. Enter your C++ instructions into a source file named Advanced25.cpp. Also, enter appropriate comments and any additional instructions required by the compiler. Display the average charge with two decimal places.

e.  Save and then run the program. Test the program using the same data used to desk-check the program.

Start your paper with an introductory paragraph. total 7-9 pages and references at least 4 sources cited.

• Prompt 1 Blockchain (2-3 pages): Explain the major components of a blockchain. Be sure to include how blockchain is affecting the global economy and how you see it growing in the future.
• Prompt 2 Big Data (2-3 pages): Describe your understanding of big data and give an example of how you’ve seen big data used either personally or professionally. In your view, what demands is big data placing on organizations and data management technology?  How does big data affect a global economy.
• Prompt 3 Government and Policies (2-3 pages):  Discuss the role government plays in a global economy.  Also, look at what policies are currently in place and then discuss what policies should be put in place.

Conclude your paper with a detailed conclusion section (1-2 pages long).

Your paper should meet the following requirements:

• Be approximately seven to ten pages in length, not including the required cover page and reference page.
• Follow APA7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.
• Support your answers with the readings from the course, the course textbook, and at least ten scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. The UC Library is a great place to find supplemental resources.
• Be clearly and well-written, concise, and logical, using excellent grammar and style techniques. You are being graded in part on the quality of your writing.

Find a peer-reviewed scholarly journal article discussing blockchain technology. Complete a review of the article by writing a 2-3 page overview of the article. This will be a detailed summary of the journal article, including concepts discussed and findings. Additionally, find one other source (it does not have to be a peer-reviewed journal article) that substantiates the findings in the article you are reviewing. Once you find the article, you will read it and write a review of it.  This is considered a research article review. Your paper should meet these requirements: 

• Be four pages in length, not including the required cover page and reference page.
• Follow APA 7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.
• Support your answers with the readings from the course and at least two scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. 
• Be clearly and well-written, concise, and logical, using excellent grammar and style techniques. You are being graded in part on the quality of your writing.

Appendix A: Final Project Overview In the final project, you play the role of a network consultant hired to design a new network for a company called Acme Manufacturing. Acme expects a network design document that includes your recommendations. The organization is growing and expanding their operations with the acquisition of a plant in China as well as several other offices throughout the United States. The following are the requirements for the new wide area network. • The network must be designed using all new equipment. • The design document must recommend the types of lines that should be used for each location (i.e. Ethernet, fiber, satellite, and so forth). • There are multiple departments that must be grouped logically to address security. Locations: o Headquarters—Atlanta, Georgia houses corporate operations, marketing, administrative staff, and accounting o Engineering—Atlanta, across from headquarters: houses sales and engineering o Distribution offices—Chicago, Phoenix, and New York: Each distribution office has a small sales staff and administrative staff. o Plant facility—China • Weekly meetings are held in the corporate conference room at headquarters, with people attending from multiple locations, including China, New York, Chicago, and Phoenix.
 

Develop a plan to set up a wide area network based on the scenario presented in Appendix A. Your plan must include the following:
o An overview of the company and its needs
o A logical network drawing for Acme to depict the recommended WAN
o Recommendations for the type of leased lines the company should choose at each location, how each location will connect to headquarters, and whether or not each location should be able to connect with the others
o Recommendations for what type of telecommunications system would work best for Acme: PBX or VoIP
o The IP address scheme, including the range of IP addresses, broadcast addresses, and subnets
o A VLAN to appropriately address Acme’s concerns that departments that are not grouped together are logically connected
o Recommendations for network equipment that should be placed at each location; also consider equipment based on the teleconferencing needs
o Protocols that will be used for the routers at each location
o Recommendations for wireless technology
o Recommendations for securing the network

 Windy 8-Puzzle Problem

We consider a variant of the 8-puzzle problem (http://tristanpenman.com/demos/n-puzzle) under

a windy condition. The initial state and the goal state are shown as follows: We assume that the wind.

Please look the instructions in the attachments.

Important: 

 In your report, please provide the screenshots of all outcomes, and the highlighted code segments

ˆ Data structure: priority queue for frontier set and hash table for explored set;

ˆ Calculation of f(n) = g(n) + h(n);

ˆ Adding leaves for expansion;

ˆ Picking the smallest f(n).

Each screenshot should include your usernames and the current time, which show that you did it by

yourselves.
